Researchers found that the scent of peppermint can improve cognitive functions including reasoning, problem solving, attention span, and even memory.
For their research, the participants of this particular study chewed peppermint, cinnamon or cherry flavored gums. Flavorless gum and no gum was offered to control groups. All three flavored gums, including peppermint, increased working memory and visual-motor response.
In another aspect of the research, odors were looked at. Both peppermint and cinnamon scents were shown to improve memory test scores.
These studies are interesting in that they don’t require you to ingest anything at all. Even if you don’t like the taste of mint, you can enjoy the benefits simply with the scent. Whether you purchase peppermint essential oils or grow the mint plant itself, try inhaling some of it before an important report is due or when you need a particularly great amount of focus.
